			I have worked on two 69 COPO Camaro's, one had a front spring "YP" tag and the other a "HH" tag. 
		
		
		
		
		
		
		
		
	
	Any others you guys know of that were actually used ? Mike  |

			Am curious Mike, wouldn't the L78s weigh nearly the same as a COPO and therefore have the same springs up front?

			HQ was used on the first two ZL-1 Camaros. 
		
		
		
		
		
		
			Spring selection was based on weight. A car with many options may use different springs than a low option car.
